In my first two hCG blood tests, my numbers doubled after two days. My last 3 tests they've gone up, but certainly not doubling, even in 4 days. Today I went for what I thought would be the definitive "the pregnancy is over" ultrasound. But the doctor found a heart beat and says it's developing in size as it should be for 6 weeks. I have no idea what to think. I don't want to get my hopes up again because I've already been through the grieving process and was ready for this to be over today. Anyone have any advice? This was a result of our first round of AI so I was on clomid and ovidrel.
